1 www.cs.helsinki.fi Networking project of CS bachelor students Tiina Niklander, University of Helsinki AMICT 2013, 16.10.2013 24.5.2013 Faculty of Science Department of Computer Science1

2 www.cs.helsinki.fi Bachelor: - Intro to Data Communication (obligatory) - Data Communication project (optional) - Intro to Computer Security (optional) - Network Programming (optional) Master: - Internet Protocols - Overlay and P2P Networks - more optional courses, f.g. security, mobility 24.5.20132 Faculty of Science Department of Computer Science Networking related courses in CS Degree

3 www.cs.helsinki.fi Enhance the knowledge gained at the course Conduct own small-scale research project Define research question Plan and perform the actual study Evaluate the results Report findings Create a poster presentation Maintain ’work diary’ about the project 24.5.20133 Faculty of Science Department of Computer Science Project: learning objectives

4 www.cs.helsinki.fi Duration 6 weeks Initial phase, 1-2 weeks Practise the skills needed and recall the course content Perform a guided measurement and write notes Define your own project, 1-2 weeks Description of the research question and method Approved by teacher Actual study, 2 weeks Poster preparation and presentation, 1 week 24.5.20134 Faculty of Science Department of Computer Science Project structure Spring 2013

5 www.cs.helsinki.fi Step 1: Learn to use wireshark use sample captures use exiting filters and create at least one own filter Step 2: Capture and analyse traffic Use a virtual machine in our NODES cloud (OpenStack- based) to capture some network traffic you created, capturing with tcpdump Use Wireshark to analyse the traffic 24.5.20135 Faculty of Science Department of Computer Science Initial phase: Introductory task

6 www.cs.helsinki.fi Group size 11 students preset maximum 10, but accepted all 11 applicants, 9 finished the project First-year to N-year bachelor students heterogeneous group strong own interest to communication aspects Only formal prerequisite: the intro to data comm. course additional requirements (grade level, study progress) not used 24.5.20136 Faculty of Science Department of Computer Science Attending students & prerequisites

7 www.cs.helsinki.fi Followed the model given in initial phase Capture traffic Few minutes to several hours Filter during capture (or not) Use wireshark to analyse the captured traffic Number of messages Traffic volume Traffic distribution Create graphs with wireshark to show results 24.5.20137 Faculty of Science Department of Computer Science Student projects: Basic model, half of the projects

8 www.cs.helsinki.fi 1.Skype – traffic measurement 2.Smite – UDP traffic measurement 3.Spotify – overview and simple measurement 4.Virtual network performance in OpenStack 5.Hackeire challenge – walk-through some problems 6.Internet Control Message Protocol (ICMP) – in tools nmap, ping, traceroute 7.Host Identity Protocol (HIP) – overview 8.Continuous scripting of tcpdump to database 24.5.20138 Faculty of Science Department of Computer Science Student projects

9 www.cs.helsinki.fi Excellent posters Poster examples shown in advance Feedback on drafts Most students did their first poster Some posters in English, mainly in Finnish (students were allowed to select the language) Poster session: 3 min presentation + 5 min discussion (then next poster) 24.5.20139 Faculty of Science Department of Computer Science Poster session

10 www.cs.helsinki.fi Students liked poster presentation freedom to select the project enhancing their knowledge about protocols and communication Next time: Spring 2014 Better evaluation after the second round 24.5.201310 Faculty of Science Department of Computer Science Results and future

11 www.cs.helsinki.fi Thank you! Any Questions? (Posters shown by request) 24.5.2013 Faculty of Science Department of Computer Science11
